Dr. Bruce Smith

As we reported yesterday, Chronic Wasting Disease continues its push towards western Wyoming's winter elk feedgrounds and Yellowstone National Park. In part one of Edward O'Brien's feature interview, Dr. Bruce Smith explained the science behind CWD. In short, it's a terrible, infectious disease that slowly saps the life from whitetail and mule deer, elk and even moose. There is no known vaccine or treatment, animals do not develop immunities to it and it's 100-percent fatal.

Chronic Wasting Disease is creeping closer to western Wyoming's winter elk feedgrounds and Yellowstone National Park. A retired U.S Fish and Wildlife Service biologist says this is something the public and policy-makers must pay close attention to. Dr. Bruce Smith is a former senior biologist at the National Elk Refuge in Jackson, Wyoming and author of "Where Elk Roam: Conservation and Biopolitics of Our National Elk Herd."
